When pressing backspace on Arabic ligatures (including characters with diacritics), they are removed as if they are one character.
As you might guess, readline doesn't know much about Arabic, per se. In a
UTF-8 locale, for example, it knows base characters and combining
characters.
The idea is simple: when moving backwards, move one multibyte character at
a time, ignoring combining characters, until you get to a character for
which wcwidth(x) > 0, and move point there. The algorithm for moving
forward is similar.
How should this be modified to support Arabic in a portable way?
